Hyun-Joo Kong, MS1,2 Chang-Mo Oh, MD, PhD1,2 Materials and Methods Hyunsoon Cho, PhD1,2 Incidence data from 1993 to 2012 were obtained from the Korea National Cancer Duk Hyoung Lee, MD, PhD2 Incidence Database, and vital status was followed through December 31, 2013. Kang Hyun Lee, MD, PhD1 Mortality data from 1983 to 2012 were obtained from Statistics Korea. Crude and age-standardized rates for incidence, mortality, and prevalence, and relative survival were calculated. Results A total of 224,177 cancer cases and 73,759 cancer deaths were reported in 2012, and there were 1,234,879 prevalent cases identified in Korea as of January 1, 2013. Over the past 14 years (1999-2012), overall incidence rates have increased by 3.3% 1The Korea Central Cancer Registry and per year. The incidence rates of liver and cervical cancers have decreased, while those 2 National Cancer Control Institute, of thyroid, breast, prostate, and colorectal cancers have increased. Notably, incidence National Cancer Center, Goyang, Korea of thyroid cancer increased by 22.3% per year in both sexes and has been the most common cancer since 2009. The mortality for all cancers combined decreased by 2.7% per year from 2002 to 2012. Five-year relative survival rates of patients diag- nosed in the last 5 years (2008-2012) have improved by 26.9% compared with those from 1993 to1995. + + + + + + + + + + + + + + + + + + + + Conclusion + C +o r+re s+p o +n d +e n +c e :+ Y +ou +ng -+J o +o W + o +n , +Ph +D + + + + + T +h e + K o+r e+a C+e n+t r +al C+a n+c e+r R+e g+i s t+ry +, + + + + + Overall cancer mortality rates have declined since 2002 in Korea, while incidence + N +a t+io n+a l+ C a+n c+e r +C e+n t e+r , +3 2 +3 I l+s a +n- r+o , + + + + + has increased and survival has improved. + I l+s a +nd +on +g- g+u ,+ G o+y a+n g+ 4 1+0 -+76 9+, K+o r+e a + + + + + + T +e l :+ 8 2 +-3 1+- 9 +20 -+2 0 +15 + + + + + + + + + + + + + F +a x +: 8 2+- 3 +1- 9+2 0 +-2 1+7 9 + + + + + + + + + + + + + E +-m +a i l+: a +st r +a6 7+@ +nc c+.r e+.k r+ + + + + + + + + + Key words + + + + + + + + + + + + + + + + + + + + Incidence, Mortality, Survival, Prevalence, Neoplasms, Korea + R +e c +ei v +e d + F +eb r+u a+r y + 1 7 +, 2 +01 5+ + + + + + + + + + A +c c +e p +te d + F +e b +ru a+r y + 2 2+, 2 +0 1 +5 + + + + + + + + + P +u b +li s +h e d+ o +n l i+n e + M +a r+c h + 3 , +2 0 1+5 + + + + + + + + + + + + + + + + + + + + + + + + + + + Introduction 1. Data sources The Ministry of Health and Welfare, Korea, initiated a Cancer has been the leading cause of death in Korea since nationwide hospital-based cancer registry called the Korea 1983 [1] and is the most burdensome disease [2]. More than Central Cancer Registry (KCCR) in 1980. The registry 210,000 new cancer cases are diagnosed in Korea each year, collected 80%-90% of cancer cases annually from more than and cancer is responsible for one in four deaths [3]. This 180 training hospitals throughout the country. article reports the most recent nationwide cancer statistics in In 1999, the KCCR expanded cancer registration to cover Korea, including incidence, mortality, survival, prevalence, the entire population under the Population-Based Regional and their trends.
